Today I was watching The Empire Strikes Back with my 3 year old son. It was his request. He wanted to see "Luke Skywalker in the snow". What can I say, the boy has impeccable taste in cinema. When we got to the big fight between Luke and Vader, Kirk shouted, "Luke has a blue lightsaber". I replied, "Yes, I know, and do you know whose lightsaber it is?" He looked at me like I was an idiot and instantly stated, "Master Obi Wan's".
This is where I found myself in the most agreeable of disagreements of my life. I told him that while Obi Wan gave the lightsaber to Luke, it originally belonged to Anakin. Therefore both lightsabers in the battle belonged to Darth Vader. He gave me one of those stop-fucking-with-me-because-I'm-only-three looks and told me I was crazy, and then we actually debated it for several minutes. While eating fish sticks. The moment was absurd to me, but I was in nerd daddy heaven.
He wasn't convinced. He even got a little pissy about it. Eventually I had to tell him that I was, like, lots older than him, and that I knew Star Wars way better, and that it was naptime. End of story. Ha! I rule!
